Ionic vs. Covalent Lewis Structures

Postby JamieVu_2C » Sun Oct 27, 2019 3:38 pm

What is the difference between drawing Lewis structures for an ionic vs covalent compound? Is it only adding or subtracting the electrons for a cation or anion, respectively?

Lewis structures for covalent bonding use lines to represent the sharing of electrons. Lewis structures for ionic bonding do not use lines because electrons are either lost or gained, not shared, so the dots (aka electrons) are moved from one element to the other to represent bonds, and brackets are used to show which element the electrons "belong" to.

In ionic bonding, electrons are transferred from one atom to another (adding electron for anion, subtracting electron for cation). In covalent bonding, electrons are shared between atoms.
